Thanks for the suggestion. but what I did was, I requested a refund on my previous payment and resubmitted a full payment including the RPRF with the official receipt. Then I attached a screenshot of the fees I paid as the receipt didn't indicate how much is the application fee and how much is the biometrics. I also sent them a webform request on the application to make sure they listed the correct amount of fees, and filed a serval complains to ask them to educate their staff better. This really sucks.
